I am running Code::Blocks version Code::13.12 on macOS Version 10.14.6The compiler I use is GNU GCC Compiler

When I try to build and run any code by either clicking Build > Build & Run or just F9, I get the message "It seems that this project has not been built yet. Do you want to build it now?" Then, whether I click "No," "Cancel," or "Yes," the same thing happens: nothing.

For example/dummy code, if I run:

#include <iostream>

using namespace std;

int main(){ char box = 'z'; cout << box << endl << box << endl;

return 0;}

that prompt saying "It seems your project has not been built yet" comes up.
